Should I do this dare to get accepted to this frat?

I'm pledging a Frat at SJSU. I lost at a poker game and now my dare is to run naked through the school cafeteria. if I don't do it, I'll be de-pledged and forbidden from this frat. I'm kind of a chub with a small . DOn't have much friends here and really want to be in this fraternity. So what should I do? should I do the dare? What could happen?
